Updated Unite.vim to version 4.1.
Updated neocomplcache to version 7.2.
Mapped U to u for vim compability. I was being mistaken after switching
to vimperator after using vim, confusing U to u for tab undo.
Updated Neosnippet to 3.0.
Escaped pipe (|) with backspace (\) in mapping.
Updated netrw to version v147g.
Added mapping for <Backspace> to behave exactly like -, which goes one
directory up.
Disabled Headlights.vim temporarily until the python bug is fixed.

Errors are so disturbing.
Updated ZoomWin to version v25f.
